13 Extension and modification

The VT-MRPA1-2X must be neither extended nor converted.

The devices are usually not susceptible to faults, as far as prescribed operating and

ambient conditions are complied with.

▶

Always work systematically and purposefully, even when under time pressure.

Random and imprudent disassembly and readjustment of settings can, in the

worst-case scenario, result in the inability to determine the original cause of

error.

▶

First obtain a general overview of how your device works in conjunction with the

entire system.

▶

Try to determine whether the device worked properly in conjunction with the

entire system before the troubles occurred.

▶

Try to determine any changes of the entire system in which the device is

integrated:

– Were there any changes to the product's operating conditions or operating

range?

– Were there any changes (e.g. retrofit) or repairs carried out on the complete

system (machine/system, electrics, control) or on the device? If yes, which?

– Was the device or machine used as intended?

– How did the fault become apparent?

▶

Try to get a clear idea of the cause of error. If possible, ask the direct (machine)

operator.

You can find the technical data of your device in data sheet

RE 30220.
